Open educational resources (OER) are free teaching and learning materials that are in the public domain or released under an open copyright license. These materials can be accessed, repurposed, adapted, and redistributed for free. Rooted in the human right to education, OER gained attention by making information and education more affordable and accessible, especially as tuition at colleges and universities increased. While conversations about their use have focused on academic and school libraries, OER have much to offer public libraries.
